[cost\_intel] Using real-time Chat Completions for large-scale backfill jobs costing 50% more than necessary

Migrate non-urgent workloads to Batch API for 50% cost reduction; accept 24-hour SLA for completion in exchange for halving per-token pricing

Journey Context:
OpenAI's Batch API offers 50% discount on per-token pricing compared to standard Chat Completions, but with 24-hour latency guarantee rather than real-time. Trap: using the standard API for bulk processing \(embeddings generation, dataset labeling, backfills\) where immediate response isn't needed. The cost difference is massive at scale: 50% off input and output tokens. Alternative of using smaller models to save cost introduces quality degradation that may require reprocessing. The Batch API allows up to 50,000 requests per file with higher rate limits. Quality is identical to standard API \(same models\), just async. Signature: if your logs show high volumes of /chat/completions with retry logic for rate limits, you should be using Batch API.
